One -1 is allowed as wildcard, which calculates this dimension automatically. 20 21 ### Returns 22 23 Type | Description 24 ---- | ----------- 25 * | Array | Matrix | A reshaped clone of matrix `x` 26 27 28 ### Throws 29 30 Type | Description 31 ---- | ----------- 32 TypeError | If `sizes` does not contain solely integers 33 DimensionError | If the product of the new dimension sizes does not equal that of the old ones 34 35 ## Examples 36 37 ```js 38 math.reshape([1, 2, 3, 4, 5, 6], [2, 3]) 39 // returns Array [[1, 2, 3], [4, 5, 6]] 40 41 math.reshape([[1, 2], [3, 4]], [1, 4]) 42 // returns Array [[1, 2, 3, 4]] 43 44 math.reshape([[1, 2], [3, 4]], [4]) 45 // returns Array [1, 2, 3, 4] 46 47 const x = math.matrix([1, 2, 3, 4, 5, 6, 7, 8]) 48 math.reshape(x, [2, 2, 2]) 49 // returns Matrix [[[1, 2], [3, 4]], [[5, 6], [7, 8]]] 50 51 math.reshape([1, 2, 3, 4], [-1, 2]) 52 // returns Matrix [[1, 2], [3, 4]] 53 ``` 54 55 56 ## See also 57 58 [size](size.md), 59 [squeeze](squeeze.md), 60 [resize](resize.md)
